GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 565,878, dated August18, 1896. Application filed October 19, 1395. Serial No. 565,275. on)model.)

To all whom it may concern:

Be it known that I, CHARLES W. BUFFING- TON, a citizen of the UnitedStates, residing at Cleveland, in the county of Ouyahoga, State of Ohio,have invented certain new and useful Improvements in Gas-Burners, ofwhich the following, with the accompanying drawings, is a specification.

My invention relates to what is known as the Welsbach system ofgas-burners for incandescent illumination.

The object of my invention is to so improve the construction of suchburners that easy access is afiorded to the burner-sieves for cleaningand other purposes without disturbing the incandescent mantle orexposing it to accidental injury.

With this object in view my invention consists in the details ofconstruction and combination of parts described herein and definedin'the claims.

In the drawings, Figure 1 is an elevation of a lVelsbach incandescentgas-burn er embodying my invention. Fig. 2 is a descriptive figureillustrating the separation of the parts of the burner as provided by myinvention for cleaning the sieves. Fig. 3 is a central vertical sectionof Fig. 1, the mantle and its supportingframe not being shown. Fig. 4 isa view of the top of the burner-head. Fig. 5 is a plan of the'burner-head with the top removed. Fig. 6 is a view of the bottom ofthe burner-head. Fig. 7 is a view of the top of the air-receivingchamber. Fig. 8 is an elevation of the burnertube, and Fig. 9 shows thelower end of the burner-tube. Fig. 10 illustrates the upper side, andFig. 11 shows the lower side, of the gallery.

The burner-tube A is the well-known form of Bunsen burner, consisting ofa straight tube provided with an internally-threaded attaching thimble Aat its lower end for securing the burner to a gas-supply pipe, anannular bead a above the thimble for supporting the airchamber 0 withits superimposed weight, and the radial air-ports a. The lower end ofthe burner-tube A is closed by a disk B, having perforations b for thepassage of gas therethrough.

The air-receiving chamber 0 is of the form shown, having an openingvertically through its base-plate and crown-plate to allow the chamberto be passed over the burner-tube A. The base-plate of thereceiving-chamber O is provided with air-inlets c. The hole 0 throughthe crown-plate is small enough so that the inner edge of thecrown-plate will engage the annular bead a. The air-chamber and itssuperimposed weight are supported by this head, as shown by Fig. 3. Anannular engagin g band D is rigidly attached to the upper side of theair-chamber. a

At the top of' the burner-tube A is the burner-head. The burner-headconsists of the cup-shaped part E, having the reduced hollow shank F,terminating in the clamp F, and the removable cap-piece G, provided withthe sieve G, the cup E having a sieve E within it. The lower sieve E isof coarser mesh than the upper sieve G. The burner-head is held upon thetop of the burner-tube A by the clamp F. This clamp,while it holds thehead firmly when in place, permits it to be easily removed from theburner-tube and to be replaced by pulling it off and pushing it on.

The chimney-gallery I-I supports the chimney I upon its open frame floorI-I, while the sides of the gallery sustain the chimney laterally. Anannular thimble J, attached to the open floor IT, projects above it.This thimble is of a diameter that will receive the burner-head. The capG of the burner-head projects a little above the thimble J. The galleryis supported from the air-chamber by a bracket, which consists of theannular base K and the braces K. The annular base K fits over, but isremovable from, the annular band D and rests upon the upper plate of theair-chamber. The braces K are rigidly attached to the base K and to thegallery H.

A mantle L is suspended over the burnerhead within the chimney by meansof the vertically-adjustable support M.

Heretofore when it was desired to clean the sieves of the burner-head ithas been necessary to remove the chimney and the mantle from the burnerto gain access to the burnerhead, and the burner-head has been difficultto clean even after the chimney and the mantle were removed, because itwas irremovably fixed within the thimble or band J of the gallery. Themantles used in these incandescent gas-burners are made of a verydelicate fabric or textile treated chemically and are so frail thatoften the slightest touch breaks and injures them. This has been asourceof great annoyance, inconvenience, and expense to users of theseburners.

By my improvement it is not necessary to remove either the chimney orthe mantle from the gallery. The gallery is separable from the otherparts of the burner, carrying with it the chimney with the inclosedmantle in position, and the burner-head is exposed free of anyenvironment. The mantle is subjected to no handling, and the chimneybeing over it constantly protects the mantle from all external injury,and, further, as the burnerhead is removable from the burner-tube andthe cap G is removable from the lower part of the head it will be seenthat both sieves can be easily cleaned. The parts of the burner asseparated for cleaning or other purposes are shown by Fig. 2.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination, in an incandescent gas-burner, of a burner-tube, anair-chamber fitted over the burner-tube, a burner-head removably securedupon the upper end of the burner-tube, and a chimney-gallery removablysupported above the air-chamber, substantially as described.

2. The combination, in an incandescent gas-burner, of a burner-tube, anair-chamber fitted over the burner-tube, a burner-head removably securedto the upper end of the burner-tube and being provided with a removablecap having a sieve therein, and a chimney-gallery removably supportedabove the air-chamber, substantially as described.

In testimony whereof I affix my signature, in presence of two witnesses,this 15th dayof October, 1895.
